VALVE.

Application filed October 9, 1923. Serial No. 667,543.

To aZZ whom t may concern.'

Be it known that I, CHARLEs A. DAVIS, a citizen of the United States', residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Valve, of which the following is a specification.

This invention has reference to a device to be placed in storage tanks for containing gasoline or other volatile fluids whereby water which usually collects at the botto-m of a tank, may be drawn from the tank without removing the volatile fluid contained therein.

The primary object of the invention is to provide a device of this character having means to control the passage of fluid to the discharge pipe so that the fluid above the discharge pipe may be removed at the will of the operator.

vWith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinafter described, may be made within t-he scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a fragmental sectional view through a tank disclosing a device constructed in accordance with the invention as provided therein.

Figure 2 is an enlarged sectional view through the controlling valve forming a part of the device.

Referring to the drawing in detail, the reference character 5 designates a tank in which gasoline or other volatile fluids may be stored, the tank being provided with the usual filling opening 6 that is closed by the cover 7 The device forming the essence of the invention includes a discharge pipe 8 having a vertical pipe section 9 provided with external threads 10 at its upper end, and external threads 11 at its lower end.

Secured to the vertical pipe section 9 by the external threads 11 is a union 12 which has communication with the pipe 13 that is provided with a plurality of openings 14 to allow fluid to enter the vertical pipe section 9 and discharge pipe 8.

Internal threads 15 are formed at the upper end of the vertical pipe 9 and receive the threads of the removable valve seat 16, while at the lower end of the pipe section 9 are internal threads 17 that accommodate the external threads of the valve seat 18.

These valve seats 16 and 18 are formed with inclined walls 19 and internal threads 2O which internal threads are adapted to receive the threaded extensions 21 of the valve member 22 carried at the lower end of the valve stem 23. Positioned on the upper end of the vertical pipe 9 is a funnel 24 through which the fluid passes to the pipe 9 and discharge pipe 8.

It might be further stated that the rod 23 is of a length to extend in proximity to the opening 6 of the tank whereby the same is supplied with a handle 25 to permit the valve member 22 to be operated to accomplish its purpose.

In the use of the device a suitable pump not shown, operates at the discharge end of the pipe 8, whereby fluid may be drawn through the pipe 8. It is therefore obvious that with the valve 22 in a position as shown by Figure 2 of the drawing, fluid may enter pipe 8 through the vertical pipe 9 where the same may be drawn through the pipe 8 in a manner as described. Should the valve member 22 be moved to the upper end of the pipe 9 and rotated to cause the same to position itself within the threaded portion of the upper valve seat 15, the fluid in the bottom of the tank 5 will be drawn off through the pipe 13, it being understood that the fluid in the bottom of the tank 5 will contain the water and other foreign matter.

I claim A device for removing fluid from the bottoms of storage tanks comprising a horizontal pipe having a vertical pipe section formed at one end thereof, the vertical pipe section having interior and external threads disposed adjacent to its ends, a horizontal pipe having a plurality of openings formed therein v and disfosedn in spacedy relation throughout the length thereof to admit fluid to the vertical pipe, removable valve seats threaded for positioning within the threaded portions ofthe Vertical pipe section the upper portion of the vertical pipe see- 10 and having internal threads, a valve member having inclined surfaces adapted to engage the valve seats, said valve having threaded upper and lower portions adapted to t in the threaded portions of the valve seats to lock the valve against vertical movement, and a funnel moumnted opmthe 11p-per end of the pixtioaImi'ipy section to admit fluid to tion.
